Each class and subclass of RPS and APS has its own percentage obligation for compliance; those percentages rise each year in the case of RPS Class I and APS, but not for RPS Class II. Beyond 2020 the RPS Class I and APS programs are scheduled to continue to grow annually at 1% and 0.25% respectively. The RPS I Solar Carve-Out, RPS Solar Carve-Out II, and RPS Class II Renewable Minimum Standards are set each August for the following year; the standards are based on formulas that take into account current market conditions. Each year the Retail Suppliers must show that they have purchased a sufficient amount of Renewable Energy Certificates (RECs), Alternative Energy Certificates (AECs), Waste Energy Certificates (WECs), Solar Renewable Energy Certificates (SRECs), and Solar Renewable Energy Certificate IIs (SREC IIs) to meet the Minimum Standard for that class. In general, the Retail Supplier determines the number of certificates that are needed each Compliance Year by multiplying their total annual sales times the Minimum Standard.
RPS Solar Carve-Out Minimum Standard Calculations 2012-2015
The RPS Solar Carve-Out Minimum Standard is set each August per formulas contained in the Class I Regulation. The results of these calculations from prior years can be found on the following page.
RPS Solar Carve-Out and Solar Carve-Out II Exemptions
The RPS Solar Carve-Out and Solar Carve-Out II Programs provide compliance exemptions for load under contract prior to certain dates. In particular, 225 CMR 14.07(2)(a)4 and 5 exempts any load under contracts signed prior to June 28, 2013 from complying with a Solar Carve-Out Minimum Standard higher than what would have existed had the Solar Carve-Out Program Cap not been increased from 400 MW. This exemption will first apply in 2015. 225 CMR 14.07(3)(b) exempts any load under contracts signed prior to April 25, 2014 from complying with the Solar Carve-Out II Program. This exemption will first apply in 2014.
In an effort to provide transparency to market participants, DOER requested that all retail suppliers provide projections of the number of MWh that they will serve to customers under contracts that qualify for each of these exemptions through 2019. The aggregate data collected from all suppliers provides information on how the exemptions are expected to reduce market demand for both SREC and SREC II certificates. The following spreadsheet contains the aggregate information collected, with the first tab containing data on the Solar Carve-Out exemption and the second containing data on the Solar Carve-Out II exemption.
2017 RPS Class II Renewable Energy Minimum Standard
The RPS Class II Renewable Energy Minimum Standard is set each August per a formula contained in the Class II Regulation. The 2017 Minimum Standard calculation is detailed in the following document:
The 2016 Minimum Standard calculation is detailed in the following document:
Compliance Year Load Obligations
Annual Compliance obligations are assessed based on the total load served by Retail Suppliers. DOER obtains the final retail load obligation after the close the calendar year, and before the close of the REC trading year, in order to determine the total compliance obligation. For 2016, total retail sales in Massachusetts equaled 46,864,431 MWh. The following table contains the total load obligations figures for current and past compliance years.
